Cov Ntawv Thov & Kev Siv Tshwj Xeeb ntawm Erbium Oxide yog dab tsi?
1. Kev Sib Txuas Lus Fiber Optical
Erbium oxide yog lub hauv paus dopant rau erbium-doped fiber (EDF). Siv nws lub zog optical amplification ntawm 1550 nm, nws yog siv los tsim erbium-doped fiber amplifiers (EDFA), txhawb nqa kev sib txuas lus optical ntev, muaj peev xwm siab.
2. Cov Khoom Siv Laser
Siv los tsim cov erbium-doped YAG laser crystals thiab erbium-doped iav lasers, emitting ib ncig ntawm 1.5 μm (qhov muag-safe band). Dav siv rau hauv kev phais mob (kho tawv nqaij, kho hniav), kev zoo nkauj (tshem tawm qhov chaw, rov ua kom tawv nqaij zoo), kev tshawb fawb thiab kev lag luam cim.
3. Cov Khoom Siv Kho Qhov Muag thiab Infrared
Siv rau hauv cov lim dej infrared, cov txheej tiv thaiv kev cuam tshuam, cov khoom siv pom kev hmo ntuj thiab cov iav tiv thaiv laser. Siv nws cov yam ntxwv ntawm kev nqus thiab kis infrared los txhim kho kev ua haujlwm ntawm cov khoom siv kho qhov muag thiab kev nyab xeeb.
4. Xim Iav & Ceramic
Xim paj yeeb/sakura-liab zoo tshaj plaws rau cov iav kos duab, cov iav ceramic zoo thiab cov pob zeb cuav. Muab cov xim ruaj khov, mos nrog kev tiv taus kub zoo heev, tsis cuam tshuam los ntawm qhov sib txawv ntawm huab cua hauv qhov cub.
5. Cov Khoom Siv Ci Ntxoov Ntxoo & Phosphors
Siv rau hauv cov phosphors hloov pauv uas hloov lub teeb infrared mus rau hauv lub teeb pom kev. Siv rau hauv cov ntawv lo tiv thaiv kev cuav, cov khoom tso saib pom kev thiab cov ntawv lo rau tsiaj txhu; ib qho tseem ceeb ntawm cov khoom siv luminescent tsis tshua muaj ntiaj teb.
6. Cov Khoom Siv Tshwj Xeeb
Ntxiv rau magnesium, txhuas thiab lwm yam alloys ua tau zoo kom txhim kho lub zog, tiv taus cua sov thiab tiv taus xeb. Siv rau hauv aerospace, automotive thiab lwm yam kev lag luam engineering siab heev.
7. Catalysis & Cov Tshuaj Zoo
Ua haujlwm ua tus txhawb nqa lossis cov khoom ntxiv rau kev tawg roj av, kev ntxuav cov pa tawm hauv tsheb thiab cov tshuaj catalysts organic synthesis, txhim kho kev ua haujlwm thiab kev xaiv. Qhia txog lub peev xwm hauv kev tshuaj ntsuab thiab kev siv rau ib puag ncig.
Kev Ceev Faj Txog Kev Khaws Cia, Kev Thauj Mus Los & Kev Ua Haujlwm
Khaws cov hmoov kom kaw, txias, qhuav thiab deb ntawm lub teeb; khaws cov av noo hauv qab 40% kom tsis txhob muaj av noo thiab CO₂ nqus tau.
Hnav lub npog ntsej muag thiab tsom iav thaum tuav kom tiv thaiv kev ua pa tsis taus.
Siv cov thawv iav uas kaw tau cua, cov thawv ceramic lossis cov thawv yas uas muaj hau kaw.
Tsis txhob kov cov hlau uas muaj zog ntev ntev.
